UM1770Y-xx 具有使能功能的500mA，微功耗，超低压差线性稳压器
功能特点
单通道线性稳压器（输出电流为500mA） Single Channel 500mA Output Current LDO
The UM1770Y-xx series are VLDO (very low dropout) linear regulators designed for low power portable applications. Typical output noise is only 90μVRMS (Fixed Output, VOUT=1.0V) and maximum dropout is just 320mV at the load current of 500mA.The internal P-channel MOSFET pass transistor requires no base current, allowing the device to draw only 250μA during normal operation at the maximum load current of 500mA.
Other features include high output voltage accuracy, excellent transient response, under voltage lockout, stability with ultra low ESR ceramic capacitors as small as 1μF, short-circuit and thermal overload protection and output current limiting.
The UM1770Y-xx series are available in SOT89-5 package.
